Description

  The present invention relates to an adhesive tape attaching device and an attaching device for cutting and sticking the adhesive tape to a predetermined length when the electronic component is mounted on a substrate such as a liquid crystal display panel with an adhesive tape. It relates to how to wear.

  When mounting a TCP (Tape Carrier Package) as an electronic component on the side of the substrate, mounting is performed using an adhesive tape (ACF) made of an anisotropic conductive member. In that case, the adhesive tape is attached in advance to the side portion of the substrate, and a plurality of TCPs are mounted on the side portion at a predetermined interval.

  However, if a plurality of TCPs are stuck at a predetermined interval after sticking the adhesive tape to the side of the substrate, the portion of the adhesive tape located between adjacent TCPs may be wasted.

  Therefore, the adhesive tape is cut into a length that is substantially the same as the width dimension of the TCP, and the adhesive tape is attached to the TCP. A plurality of TCPs are mounted on a side portion of the substrate at a predetermined interval so as not to waste the adhesive tape.

  A sticking apparatus for sticking an adhesive tape cut to a predetermined length on a TCP has a supply reel as a supply unit. A release tape having the adhesive tape attached thereto is wound around the supply reel. The release tape to which the adhesive tape is attached is pulled out from the supply reel, guided by a guide roller, and intermittently run by a predetermined length by a transport mechanism including a transport chuck.

  The adhesive tape that is intermittently pulled out by a predetermined length together with the release tape from the supply reel is cut into a length corresponding to the width of the TCP by a cutting mechanism. A sticking means is provided in the conveyance path of the release tape, and the TCP is positioned at a sticking position, which is a position corresponding to the sticking means, and stands by.

  When the pressure-sensitive adhesive tape cut to a length corresponding to the width dimension of TCP is conveyed to the attachment position of the TCP, the pressure-sensitive adhesive tape is pushed up while being heated by a pressure tool via a release tape. And attached to the TCP.

  When the adhesive tape is attached to the TCP, the release tape is peeled from the adhesive tape. After peeling, the release tape is run by a predetermined length by the feeding mechanism, so that the adhesive tape cut to the predetermined length by the cutting mechanism is sequentially positioned at the adhesive position, and the adhesive tape is attached to the TCP. It is done repeatedly.

  As the feeding mechanism that travels by intermittently feeding the adhesive tape by a predetermined length, the above-described pair of transport chucks disposed on the downstream side in the traveling direction of the release tape from the adhesive position is used. The pair of transport chucks are separated at a predetermined interval, and one transport chuck provided on the downstream side in the transport direction of the release tape is driven to reciprocate.

  Then, the release tape is clamped by one conveyance chuck, and the release tape is driven in the traveling direction of the release tape with the other conveyance chuck opened, thereby releasing the release tape. Run for a predetermined length.

  Next, if the release tape is clamped by the other transport chuck, the state where the release tape is clamped by one transport chuck is released, and this one transport chuck returns to its original position. The release tape is intermittently run by a predetermined length.

JP 2010-080874 A

  By the way, when the adhesive tape attached to the release tape is cut to a predetermined length and attached to TCP, an extraction part is provided between the adhesive tapes to be cut to a predetermined length, and the extraction part is removed. An interval is formed between the adhesive tapes cut to a predetermined length. Thereby, only the adhesive tape cut to a predetermined length is surely pressed against the TCP so that it can be attached.

  However, if the adhesive tape is cut to a predetermined length and the extraction part between the adhesive tapes cut to the predetermined length is removed, a part of the adhesive tape remains on the release tape when the extraction part is formed. In this state, the release tape may be sent to the feeding mechanism.

  The release tape with the adhesive tape remaining is sent to the feed mechanism. When the release tape is run by repeatedly holding and releasing the release tape by the pair of transport chucks of the feed mechanism, the release tape is released by the residual adhesive tape. The tape sticks to the conveyance chuck and becomes entangled, and the release tape cannot be reliably run.

  Also, when a new supply reel is replaced or when the operation of the mounting apparatus is resumed, the adhesive tape that has been cut to a predetermined length is not attached to the TCP at the attachment position, and the release tape is attached to the transport chuck. Sometimes it is sent to. In such a case, the adhesive tape remaining on the release tape may be entangled with the chuck and the release tape cannot be conveyed.

  An object of the present invention is to provide an adhesive tape sticking apparatus and a sticking method in which a release tape in a state in which an adhesive tape remains is not sent to a feeding mechanism.

Embodiments of the present invention will be described below with reference to the drawings.
1 to 3 show a first embodiment of the present invention, and the adhesive tape attaching apparatus shown in FIG. 1 includes a supply reel 11 as a supply unit. As shown in FIG. 2, a release tape 13 having an adhesive tape 12 attached to one side surface is wound around the supply reel 11. The adhesive tape 12 is an anisotropic conductive member in which metal fine particles are mixed in a thermosetting resin having adhesiveness on both sides, and the release tape 13 is formed into a tape shape having the same shape as the adhesive tape 12 by a synthetic resin. Has been.

  The release tape 13 is drawn downward together with the adhesive tape 12 from the supply reel 11 and is turned upward so that it is engaged with the dancer roller 15 having the weight 14 and given tension.

  And it engages with a pair of guide rollers 16a and 16b spaced apart at a predetermined interval in the horizontal direction, and runs horizontally with the surface to which the adhesive tape 12 is attached facing upward. The dancer roller 15 is provided to be movable in the vertical direction along a guide (not shown).

  In the release tape 13, the traveling direction is converted downward by a guide roller 16b on the downstream side in the transport direction from a state where the release tape 13 travels horizontally, and a part thereof is a pair of sandwiching pieces 17a that are driven to open and close the holding chuck 17 and the feed chuck 18. , 18a are sequentially passed through and are collected in the collection tank 19. The holding chuck 17 and the feed chuck 18 constitute a feed mechanism 20.

  The holding chuck 17 is driven to open and close by a first opening / closing drive source 22 such as a cylinder, and the feed chuck 18 is driven to open and close by a second opening / closing drive source 23 such as a cylinder and is also driven by a vertical drive source 24 such as a cylinder. The two open / close drive sources 23 are integrally driven with a predetermined stroke in the vertical direction.

  The first opening / closing drive source 22, the second opening / closing drive source 23, and the up / down drive source 24 are controlled by a control device 25 shown in FIG. That is, when the holding chuck 17 is opened, the feed chuck 18 is closed by the second opening / closing drive source 23 and the release tape 13 is clamped, and in this state, the feed chuck 18 is moved to a predetermined stroke by the vertical drive source 24. Is driven downward. The moving direction of the feed chuck 18 at this time is indicated by an arrow in FIG.

  Thereby, the release tape 13 is fed by the feed chuck 18 at a predetermined length corresponding to the stroke against the tension applied by the dancer roller 15. The feed direction of the release tape 13, that is, the traveling direction is indicated by an arrow X in FIG.

  When the release tape 13 is fed by the feed chuck 18, the holding chuck 17 is closed by the first opening / closing drive source 22 to hold the release tape 13. Next, after the feed chuck 18 is opened and driven to the raised position, it is driven in the closing direction to sandwich the release tape 13. At the same time, the holding chuck 17 is opened, and the feed chuck 18 is driven in the downward direction indicated by the arrow in FIG. 1 by the vertical drive source 24 to feed the release tape 13 by a predetermined length.

  In the portion where the release tape 13 is vertically changed by the dancer roller 15, a belt-like support is provided on the other side opposite to the side where the adhesive tape 12 of the release tape 13 is attached. A member 27 is provided. The release tape 13 travels along the plate surface of the support member 27.

  As shown in FIG. 2, a pair of cutting lines 28a are formed on the pressure-sensitive adhesive tape 12 attached to the release tape 13, as shown in FIG. A cutting mechanism 31 for forming the extraction part 28b in the adhesive tape 12 is provided.

  The cutting mechanism 31 includes a cutting cylinder 32 as a drive source arranged with its axis orthogonal to the side surface of the release tape 13 and a pedestal 33 connected to a rod 32a of the cutting cylinder 32. It is constituted by a pair of cutting blades 34 provided at a predetermined interval.

  When the cutting blade 34 is driven by the cutting cylinder 32 toward the adhesive tape 12 affixed to the release tape 13 as indicated by the arrow S in FIG. 2, the pair of cutting blades 34 are attached to the adhesive tape 12. A pair of cutting lines 28a is formed. That is, the extraction part 28 b is formed in the adhesive tape 12.

  When the extraction portion 28b is formed in the adhesive tape 12, the release tape 13 is intermittently conveyed at a pitch P (shown in FIG. 2) corresponding to the stroke of the feed chuck 18 of the feed mechanism 20. As a result, the extraction part 28 b formed on the adhesive tape 12 by the cutting mechanism 31 is positioned opposite to the extraction mechanism 36.

  The extraction mechanism 36 has an extraction cylinder 37 as a drive source, and a pedestal 38 is provided on a rod 37 a of the extraction cylinder 37. The pedestal 38 is provided with a pressing portion 38a, and a sticking tape 39 that runs from a supply reel and is wound around a take-up reel (both not shown) is stretched on the front end surface of the pressing portion 38a. Has been.

  When the extraction cylinder 37 is operated and the adhesive tape 39 is pressed by the pressing portion 38 a against the extraction portion 28 b formed on the adhesive tape 12, the extraction portion 28 b is attached to the adhesive tape 39. Has been removed.

  As shown in FIG. 3, the operation of the cutting cylinder 32 and the extraction cylinder 37, that is, the supply and discharge of compressed air to the cylinders 32 and 37 via control valves (not shown) are performed by the control device 25. Is called.

  In this way, if the extracted portions 28b formed on the adhesive tape 12 at the predetermined pitch P by the cutting mechanism 31 are adhered and removed by the adhesive tape 39 of the extraction mechanism 36, the adhesive tape 12 has a predetermined length. The cut portion 12a is divided. This cutting part 12a is set to have substantially the same length as the width dimension of the TCP 42 as an electronic component described later.

  The stroke of the feed chuck 18 driven by the vertical drive source 24 can be changed. Thereby, the length of the cutting part 12a of the adhesive tape 12 cut by the cutting mechanism 31 can be set according to the size change of the TCP 42 or the like.

  After the adhesive tape 12 is cut into the predetermined length of the cutting portion 12a, when the pitch feeding of the release tape 13 by the feeding mechanism 20 is repeated a plurality of times, the cutting portion 12a waits with the TCP 42 positioned. It is conveyed to the sticking position B (shown in FIG. 1).

  At the sticking position B, a rotary table 44 is provided above the cutting portion 12a of the adhesive tape 12 conveyed to the sticking position B. The rotary table 44 is provided with a plurality of holding portions 45 at a predetermined angle in the circumferential direction.

  Each holding portion 45 holds the upper surface of one end in a direction intersecting the width direction of the TCP 42 by suction, and a cut portion 12a of the adhesive tape 12 is adhered to the lower surface of the one end. The TCP 42 sucked and held by the holding portion 45 is positioned slightly above the cutting portion 12a of the adhesive tape 12 that has been transported and positioned to the sticking position B.

  The rotary table 44 is rotationally driven by a predetermined angle by a rotational drive source 46 controlled by the control device 25 as shown in FIG. Accordingly, the holding part 45 holding the TCP 42 by suction is sequentially positioned above the sticking position B.

  As shown in FIG. 1, a sticking means 47 is provided below the release tape 13 at a position facing the rotary table 44. The sticking means 47 has a pressing tool 48 having a planar shape slightly larger than the cutting portion 12a. The pressurizing tool 48 is driven in the vertical direction by a vertical cylinder 49 whose drive is controlled by the control device 25.

  The pressure tool 48 has a built-in heater 50, which is heated to a predetermined temperature, that is, a temperature at which the adhesive tape 12 can be reliably attached to the TCP 42. Although not shown in detail, energization of the heater 50 is also controlled by the control device 25.

  When the up / down cylinder 49 is actuated and the pressurizing tool 48 is driven in the upward direction, the cut portion 12a of the adhesive tape 12 positioned at the adhering position B is adhered to the adhering via the release tape 13. It is stuck to the TCP 42 held by the holding part 45 positioned at the position B.

  When the cut portion 12a is attached to the TCP 42, the release tape 13 is peeled from the cut portion 12a by a release roller (not shown). Next, the rotary table 44 is rotated by a predetermined angle, and a new TCP 42 is positioned at the sticking position B. The TCP 42 to which the cutting part 12a of the adhesive tape 12 is attached is transferred from the holding part 45 to a mounting tool and mounted on a substrate (both not shown) such as a liquid crystal display panel.

  As shown in FIG. 1, the adhesive tape 12 remaining on the release tape 13 is positioned downstream of the sticking position B in the running direction of the release tape 13 and upstream of the feed mechanism 20. Residue removing means 53 for removing is provided. Specifically, of the pair of guide rollers 16a and 16b guided so as to run the release tape 13 horizontally, the residue removing means 53 is located at a position facing the guide roller 16b located on the feeding mechanism 20 side. Is provided.

  The residue removing means 53 has a base plate 54 that is fixedly arranged. The base plate 54 is provided with a supply reel 56 on which an adhesive removal tape 55 is wound, and a take-up reel 57 for winding the removal tape 55 fed out from the supply reel 56.

  A portion of the removal tape 55 located between the supply reel 56 and the take-up reel 57 is pressed by a pressing roller 58. The pressing roller 58 is rotatably provided at the tip of the rod 59a of the pressing cylinder 59. When the pressing cylinder 59 is operated, the pressing roller 58 is urged in the pressing direction of the removal tape 55. In this embodiment, the pressing roller 58 and the pressing cylinder 59 constitute pressing means.

  When the pressing roller 58 is urged by the pressing cylinder 59, the removing tape 55 pressed by the pressing roller 58 has the adhesive surface thereof attached to the guide roller 16b and the adhesive tape 12 of the release tape 13 is pasted. Press contact with the upper surface.

  The take-up reel 57 removes the removal tape 55 in synchronization with the travel of the release tape 13 that is intermittently pitch-fed by the feed mechanism 20 by the take-up drive source 61 shown in FIGS. Is driven in the direction indicated by arrow F.

  As a result, the removal tape 55 sticks and removes the adhesive tape 12 partially remaining on the upper surface of the portion of the release tape 13 that travels in a horizontal state. The pressing cylinder 59 and the winding drive source 61 are controlled by the control device 25.

  A brake mechanism (not shown) is provided on the supply reel 56 of the residue removing means 53, and the brake mechanism prevents the supply reel 56 from freely rotating below a predetermined torque. Thereby, the supply reel 56 is freely rotated and the removal tape 55 is fed out and prevented from being loosened.

  According to the sticking apparatus having the above-described configuration, the release tape 13 is intermittently pulled out from the supply reel 11 by a predetermined length by the feed mechanism 20, and the adhesive tape 12 is stuck by the pair of guide rollers 16a and 16b. The vehicle is guided horizontally with the surface facing up.

  The adhesive tape 12 adhered to the release tape 13 is cut and formed by the pair of cutting blades 34 of the cutting mechanism 31 before reaching the upstream guide roller 16a. Each time the release tape 13 is conveyed by the feed chuck 18 of the feed mechanism 20 with a predetermined stroke, the extraction portion 28 b is removed by the sticking tape 39 of the extraction mechanism 36. As a result, the adhesive tape 12 adhered to the release tape 13 is divided into cut portions 12a having a predetermined length.

  Thus, when the cut part 12a of the divided adhesive tape 12 reaches the sticking position B, the pressurizing tool 48 of the sticking means 47 is driven in the upward direction by the vertical cylinder 49. As a result, the cutting part 12a of the adhesive tape 12 is pressed while being heated on the lower surface of the TCP 42 which is held and positioned by the holding part 45 of the rotary table 44 at the sticking position B. Affixed to.

  Even if the cut portion 12 a of the adhesive tape 12 is stuck to the TCP 42 at the sticking position B, the adhesive tape 12 is cut and formed on the upper surface of the release tape 13 by the pair of cutting blades 34 of the cutting mechanism 31. Some of them may remain as residues.

  However, on the upper surface of the release tape 13, the adhesive surface of the removal tape 55 of the residue removing means 53 is located downstream of the sticking position B in the traveling direction and upstream of the feed mechanism 20. Is fed in synchronism with the travel of the release tape 13 while being pressed and contacted by a pressing roller 58 as a pressing means. Thereby, even if a part of the adhesive tape 12 remains on the upper surface of the release tape 13, the residue is adhered and removed by the removal tape 55.

  As a result, the release tape 13 to which the adhesive tape 12 is adhered and remained is not sent to the feed mechanism 20 provided on the downstream side of the residue removing means 53. Therefore, the release tape 13 is held by the feed mechanism 20. It is possible to prevent the release tape 13 from being smoothly conveyed by being attached to the chuck 17 and the feed chuck 18 and entangled.

  Moreover, the adhesive tape 12 remaining on the release tape 13 can be reliably removed by the removal tape 55 being always in contact with the upper surface of the release tape 13 and being sent in synchronization with the running of the release tape 13. Will be done.

  When the supply reel 11 around which the release tape 13 is wound is replaced or when the operation is resumed after the operation is stopped, the cut portion 12a of the adhesive tape 12 cut to a predetermined length is attached to the TCP 42 at the attaching position B. It may be sent downstream from the sticking position B without being worn.

  Even in such a case, the adhesive tape 12 remaining on the release tape 13 can be reliably adhered and removed by the removal tape 55 of the residue removal means 53, so that the release tape 13 is held by the holding chuck of the feed mechanism 20. 17 and the feed chuck 18 can be prevented from being entangled and being unable to smoothly carry the release tape 13.

  FIG. 4 shows a second embodiment of the present invention. Note that the same parts as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted. In the second embodiment, the mold release is performed on the upstream side in the running direction of the release tape 13 relative to the residue removing means 53 and on the downstream side of the adhesive position B where the adhesive tape 12 is adhered to the TCP 42. For example, a sensor 63 such as a reflective optical sensor is provided for detecting whether or not the adhesive tape 12 remains on the tape 13.

  The detection signal of the sensor 63 is output to the control device 25 shown in FIG. When the sensor 63 detects the adhesive tape 12 remaining on the release tape 13, and the detection position, that is, the portion of the release tape 13 where the adhesive tape 12 remains approaches the pressing roller 58 of the residue removing means 53. The control device 25 operates the pressing cylinder 59.

  Accordingly, the pressing roller 58 is driven from the raised position indicated by the solid line to the lowered position indicated by the chain line, and the removal tape 55 is pressed against the upper surface of the release tape 13 as indicated by the chain line. At the same time, the take-up drive source 61 is operated to synchronize the removal tape 55 with the travel of the release tape 13 and to a predetermined length, that is, the length of the residue remaining on the release tape 13 detected by the sensor 63. Or longer than that length by a predetermined length before and after the residue with respect to the running direction of the release tape 13.

  Thereby, the adhesive tape 12 which is a residue remaining on the upper surface of the release tape 13 can be reliably removed by the removal tape 55. In addition, since the removal tape 55 is wound around the take-up reel 57 only when the adhesive tape 12 is removed from the release tape 13, the use length of the removal tape 55 is reduced, and the running cost can be kept low. It becomes possible.

  In the above-described embodiment, the case where the adhesive tape cut to a predetermined length is mounted on the TCP has been described as an example. However, the adhesive tape is attached to a substrate on which the TCP is mounted. This invention can also be applied. That is, the electronic component is not limited to TCP, and may be a substrate on which TCP is mounted.
